Z Claims.

The object of the present inventionV is to provide'a new and speedyv apparatus for inserting The method of operating the apparatus comprises the Steps of arr'anging sticks away from the plural-cavity mold which contains the frozen confections in a manner by which the sticks are given locational arrangement corresponding with the mold w cavities, the placing of the group of so arranged sticks over the mold while the latter is held in the stick pr'essing apparatus, or prior thereto, and Operating apparatus to drive the sticks si'multaneously; and each .into a frozen confection in one of the mold cavities.

Theinvention will be described with reference to the accompanying drawings, in which:

Figure 1`` is a side elevation illustrating an apparatus for inserting sticks into frozen confections by pressure together with a plural cavity mold in position thereon and a stick holder separable from the other elements and supporting sticks in registry with the mold cavity, the figure being partly broken away on the line |-l, Figure 2.

Figure 2 is a rear shown in Figure 1.

Figure 3 is an enlarged plan view of the pressing machine shown in the preceding figur'es, broken away to show the center and one end thereof.

Figure 4 is a horizontal section on the line 4-4, Figure' 1.

Figure 5 is a transver'se section on the line 5-5, Figure 1;

Referring to the drawings, the machine for inserting sticks into frozen confections consists of a base member which supports a plurality of shaft-like riser's 2 which are four in number, in the present em'bodiment. At an intermediate. point of the risers the latter pass through apertured bosses 3a: of a heavy horizontal frame plate 3 which carries a depending br'acket 4, the latter being forked at its lower end, and each forked member 4x carryng a bearing boss 5.

Rotatably held by the bearing bosses 5 is a horizontal shaft 6 and fixed to the latter intermediate the bosses 5 is a for'ked lever arm 1. Pivoted between the forks of lever arm 'I is a link 8 which in turn is pivoted to a toggle lever com;` prising the lever arms 9, 9x. Toggle arm 9 is pivoted at IO to bracket 4 and toggle arm 9a: is pivoted at ll to a saddle member 12 fixed to vertical shaft 13 by means of a str'ap M secured to saddle |2 by bolts 15.

The shaft is operated elevation of the structure by means of any suitable instrumentality as, for example, a hand lever IE. Shaft E3 rises upwardly through a bearing boss 3mm depending from frame plate 3 and at its upper end carries a flanged collar* ll secured to the lower face of a table iii. Table IB is formed with '5 laterally reinforced apertures which receive risers 2, the latter' guiding the table in its movement later to be described. Carried by the table at its upper face are two sets of opposed bracket arms |9, each set carrying a longitudinal extending l10 guide bar 20 between which the plural-cavity molds are adap'ted to be guided into position. At one or' both ends the bars 20 may be outwardly fiarecl as shown at 20:12, Figure 3.

At their top ends risers 2 receive the apertured` bosses Na: of each of two bracket members 2| having their ends bent vertically at Zima: and thence horizontally, the br'acket arms receiving between them a block-carrying plate 22,'the latter carrying rows of downwardlyprojected blocks 23, which -blocks are positioned in accordance with the rows of cavities in a multi-cavity mold of usual construction, or of desired construction as, for example, one in which there are six rows of cavities with four' cavities in each row. Each v bearing boss 2 Ex is formed with a depending section best shown in cross-section at 2 la, Figure 4, which is pivoted -at 2151 to a strap 25, the latter having a Vertical slot adapted to receive a pivoted looking stud 26 threaded at its outer end to receive a thumb nut 27.

By reason of the'construction just described, loosening of the thumb nuts will enable 'the bracket members 2! with the block plate and blocks carried thereby to be raised' or' lowered in order to accommodate different heights of frozen confections or to change the degree to which the sticks are to be pressed into the frozen confections.

In the above description it has been shown that the members IZ and Hi are clamped in fixed position upon the rod l. Below the said members the bracket 4 may be provided with a Vertical bearing apertur'e for the rod or with a semi-annular guide face at 4x formed with threaded apertures by means of which a strap 29 may be secured in position. The faces of the latter two members will be so formed as to guide shaft 13 whilst permitting its free movement, in Vertical direction.

In Figures 1 and 2 a plural-cavity mold, somewhat schematically shown, is in operative position on table Hi. The mold is shown as constructed with heavy Vertical corner members 30 between'which are held the r'ows of cavity members 3|, at the top of which will be positioned a horizontal plate formed with apertures, one for each cavity member, the plate being indicated at 3| x. Rising upwardly from the edges of plate 3| :c is the customary skirt 32 which terminates at its top with a reinforcing bead 33. At each end of the mold structure is a handle 34 bymeans of which the mold is manipulated.

In inserting the mold, it may be movedonto and along tabley |8 from the end of the pressing apparatus which is shown in plan view, Figure 3. To determine the limit of such positioning movement of the mold, there may be carried by guide bars 20 or one of the arms I9 a swinging stop member having an operative end 35, Figure 2, and a weighted lower Operating end 35x which will hold the stop in operative position and which in turn maybe moved to| swing the stop aside to enable insertion of the mold from the rear face of the apparatus, i. e., the face shown in Figure 2.

VIn Figures 1 and 2 of the drawings, the mold is shown as having received a stick-centering and holding device comprising a horizontal plate 36 which carries a plurality of depending blocks 31, arranged in rows in accordance with the rows of mold cavities. Each block will be formed with an aperture to receive a stick 38, and there will preferably be provided frictional means or spring acting means to hold the sticks in position prior to their positive movement by the stick-pressing operation. A simple type of spring-holding device for each stick is shown in Figure 1, wherein the wall of each block is formed with an aperture cut through to the stick-receiving aperture, the first aperture receiving a spring 39 carried at its upper end by block-holding plate 36.

.In practicing our method, the stick-centering and holding device may be placed upon a table with the blocks 31 lowermost and resting thereon. The sticks may then be quickly inserted through the apertures of the blocks which are designed to receive the sticks, and by their contact vvith the table the sticks will be inserted the same distance throughout. This stick-positioning operation may be performed whilst the pressing machine is in action with respect to an associated plural-cavity mold and stick-centering and holding element, and when a succeeding mold is placed in position on table |8 the thus prepared stick-centering and holding device is placed thereon with the blocks resting upon the frozen confections in the mold cavities. Thereupon hand lever |6 will move downwardly to straighten the toggle and table l8 is moved upwardly until the top of each stick engages the lower end of its appropriate fixed block 23, the latter being may be made in the form and arrangement of the elements illustrated in the drawings without departing from the spirit of the invention.
